APPARATUS FOR UTILIZING VIAVE-POWER IlatentedScpt.23, 1913.

Application filed January 2L 191-3. Serial No. 743,312.

b all whom. it may (on corn lo it known that T, AUoIrs'iWV.Mniiaxnnn, a subject of the King of Sweden, residing in the .r-ity and county of San Francisco and State of California, have invented new and useful improvements in Apparatus for Utilizing ave-Power, of which the following is a spec fication.

This invention relates to an apparatus J't'or utilizing wave power, and particularly pertains to a means for raising water by the action of waves.

It is the object of this invention to provide a simple, practical, and efficient means by which a pump can be operated by the action of waves, and which is adapted to utilize the energy of waves to a high degree.

Other objects will appear hereinafter.

The invention primarily resides in a float having an inclined end against which the waves impact, connected to a pivoted rocking frame to have an oscillating movement in a vertical direction, and a pump pivoted to have an oscillating movement and having a reciprocal piston connected to thefloat.

The invention further consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the invention with parts broken away. Fig. 2 is a plan view with the framework removed. Fig. 3 is a detail section on the line X-X of Fig. 1 showing the pivoted mounting of the. pump. Fig. 4 is a detail illustrating a modilied form of the pump mounting.

In the drawings A represents a pier or similar structure, which may be of any desired construction, and is'designed to extend over.the surface of a body of water a suitabl distance therefrom. Pivotally connected to} the pier at 2 is a depending frame which extends downwardly at an an gle, in the direction of travel of the waves, and terminates in a float 5.

The frame is constructed to have a wide transverse area, and here shown as formed of side rails 3 connected together by plates 4; the side rails 3 forming downwardly extending flanges on the edges of the plates 4 to prevent lateral spreading of a wave at the point of impact with the underside of the rocking frame. The float 5 is here shown as rigidly connected to the l'rame, and is preferably quadrilateral or l -lll 0 in form. The side b ofthe float adJaccnt the frame is inclined at an acute angle in relation to the surface of the water, and 1s a continuation of the plates at on the r irame.

,' .Pivotally connected to the float 5 is a piston rod 7 which extends upward and has a piston 8 on its outer end; the piston 8 be ng reciprocally mounted in a pump cylinder 9. lhc pump cylinder 9 is pivotally mounted in suitable hearings to permit of .an oscillating movement thereof; trunnions its upper end being provided for this purpose.

A vertically disposed stand-pipe 11 is )1'0- vided, the lower end of which extends mto the water, while its upper end leads to any suitable point of discharge. This standpipe 11 is connectcd'to the pump casing 5) either-through the trunnion 10 as shown in Fig. 3, or through a flexible connection 12 as shown in Fig. 4;. Check valves 13 and 1 1 are provided in the stand-pipe ll the checkvalve 13 being disposed below the connection with the pump casing 9, and the checkvalve let above the connection with the pump casing. The stand-pipe 11 is turned at right. angles immediately above the check-valve 14;, and connected to the stand-pipe 11, and opening thereto immediately above the vert-ical portion thereof adjacent the check valve 14 is 'an air cylinder 15 for cushioning the flow of water throughthe stand-pipe 11.

An important feature of this invention rc- 'sides in the inclined side 6 of the float 5, and the inclined oscillating frame connected therewith. The frame and the inclined side 6 of the float; 5 are so arranged in relation 'to the surface of the water that when the waves strike thcreagainst the impact of the wave will be transmitted to the float gradually. y

In the operation of the invention, a wave traveling, in the direction of the arrow (1 in Fig. l strikes the inclined side 6 of the float, or the underside of the plates 4 on the inclined frame, causing the latter to move upwa rd on' its pivotal mounting 2, the float 5 rising on the wave. As the float 5 moves -up-ward, the piston rod 7 is caused to advance in relation to the cylinder 9 of the pump, thereby moving the piston 8 up wardly therein. The upwardpnovement of 10 and 10 on the pump cylinder adjacent.

the piston in the pnm :ylinder forces such liquid :18 is displaced the piston through the connection leading to the stand-pipe ll. 1 upward through the check-valve 14, against the air cushion l5 and out through the dis i charge end of the stand-pipe. The wave on passing under the float 5 allows the latter to gravitate to a lower position, thereby retmcting the piston 8 in th.e pump casing. I The retracting movement of the. piston 5' creates a suction in the upper end of the pump cylinder and acts to drew water 7 through the stand-pipe 11. and check-valve 13 into the pump cylinder through a con nection therewith from the stand-pipe ll.

' By pivotally mounting the pump cylinder it will be caused to have an oscillating move ment as the piston rod 7 is reciproczitecl therein by the oscillating movement of the float 5. The piston rod 7 and the cylinder 9 and fall of the tide; the piston 8 Varying its position in the pump cylinder according tothe water level The pump cylinder 9 and the piston rod 7 are preferably positioned in relation to the float- 5 an angle opposite that the i l I l l l of such length as to allow for the rise l i l frame, as shown in Fig, 1. it is rnanifesti ev apex) frame pivoted at end to the fixe'tl structure having a top plate and down-- wartlly extending inclosing side plates, at he float, one end of which is closed by an inclined continuation of the top plate of the frame, a stand pipe and pump column with check valves located at :2, distance from the float, a, pumping cylinder with hollow con tlucting trimnions connected with the column, and e plunger roti extending frointhe pump cylinder and connected with the floatsupporting frame at an obtuse angle substantially as described.

In testimony whereof l have hereunto set my hand in the presence of two subscribing; 'WIHIESSES.
